SI5338J-B04983-GM

Overview

The Skyworks SI5338J-B04983-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, flexible input references up to 710 MHz, and glitchless frequency adjustments via I2C/SMBus interface in a 24-lead QFN package.

Procurement Notes

Verify the specific ordering suffix B04983 against the manufacturer's official documentation to confirm pre-programmed register settings or configuration parameters. Confirm package type and temperature range specifications match the design requirements before procurement.

Selection Notes

Select this component for designs requiring multiple independent clock frequencies from a single IC. Ensure the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) are compatible with the target load. Verify that the input reference frequency falls within the supported ranges for the chosen input mode.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. It serves as a replacement for multiple discrete crystal oscillators or acts as a frequency translator in high-performance timing applications.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the Si5338 series. Verify that any substitute part supports the same output formats and jitter specifications required by the application.
